How does it work?
The Evac wastewater handling solution is a closed system which consists of vacuum toilets, vacuum interface units, vacuum piping, vacuum collection tanks and wastewater treatment plants. The solution is based on vacuum, not gravity, which makes it possible to flush the waste horizontally or even vertically into overhead piping and, if needed, around obstacles.
The Evac solution is environmentally friendly. With low water use – up to 80 % less than used in conventional toilets – it reduces sewage volumes and thus meets the requirement of small environmental footprint. The grey waters, originating from wash basins and being flushed through the Evac wastewater handling system, are clean enough to be used for irrigation or toilet flushing.
